tools-demo-systats

Short (~25s), silent, caption-burned screen recording of systats for social media / YouTube: launches the real installed app, records the real running window (real host data, no staged scenario -- Rule 14), and burns timed captions via infrastructure-screencast's captions module. Window find/move/focus is infrastructure-screencast; the one click (expand the top ranked cause) is tools-gui-harness's hardware input.

What it is for

Pure timing/content plan for the systats demo recording. Kept separate from main.rs's I/O orchestration (launch, window control, recording, caption burn) so the schedule itself is unit-tested without touching a display, ffmpeg, or the app (Gate 2: TDD the decidable logic).

Capabilities

How to use it

No examples/ target and no doctest in this crate's rustdoc. The tests listed under Verification are the closest executable usage.

Module structure

No public modules: the crate root is its whole surface.

Public surface

`crate root`

No pub use re-exports: every item above is declared in this crate.

Boundary

Reaches into infrastructure.

Shares tier tools with 84 other crates: tools-advisory-reach, tools-archive-guard, tools-artifact-scaffold, tools-ask-ai-core, tools-ask-ais, tools-ask-gemini, tools-book, tools-book-report, … (84 total).

_What this crate deliberately does NOT own is a judgment. No committed registry records one for it, so none is stated here._

Feature flags

No Cargo features are defined: every capability is unconditional, so no consumer can receive a half-wired crate.

Targets

Error model

No public error type was detected: no public item declares a type named *Error, and no public signature returns one.

Operational characteristics

No unsafe block, unsafe fn, unsafe impl or unsafe trait was found by the parser anywhere in this crate's source.

Configuration

Related capabilities

No workspace crate depends on this one.

Verification

Evidence by module. How often each public module is named by something executable.

What the tests establish, by name:

• boundary_schedule_fits_within_recording_length — src/lib.rs
• constraint_captions_never_overlap — src/lib.rs
• valid_expand_action_happens_during_its_own_caption_window — src/lib.rs
